What does every prepubescent girl want more than anything else in the world? To be POST-pubescent. Besides that? A horse. So if you have a Supergirl then naturally you're going to need to throw a super-horse in there at some point!

So here we have Supergirl with her Super-Horse. And maybe you're thinking that, like Krypto the Super-Dog or Beppo The Marx Brother, I mean Super-Monkey, obviously a Super Horse would have to come from the planet Krypton. But you'd be wrong!

It all began that one day when DC's editors saw the sales figures for a Supergirl story that had horses in it, and saw magical dollar signs. What incredible adventures does the future hold for the Steed of Steel and his mistress Supergirl? Don't you feel strange just reading the words "the Steed of Steel and his mistress"? Doesn't it sound like copy from the back of some terrible fantasy romance? Well, buckle up pal.

One day Linda "Supergirl" Danvers, who sleeps in the brown wig that disguises her natural blonde Supergirl hair, is vacationing at the famed Supergirl Ranch. Yes, Supergirl licensed her name and image out to a dude ranch. Sure, why not.

The Dream Dictionary says "if you dream of seeing a white horse, the indications are favorable for prosperity and pleasurable commingling with congenial friends and fair women." Or maybe discovering a flying super horse right in the corral of your licensed-character dude ranch!

I don't want to, you know, read too much subtext into these stories, but... Supergirl here "brands" her "dream horse" with lipstick. Teaching girls to mark their (men) property? Larger statement about the trappings of adulthood and committment? And do they still actually brand livestock with red-hot iron? Somebody call the ASPCA!

Now let's get down to business. Why are you a flying telepathic horse with super powers? Well, let's begin at the beginning in ancient Greece, when I was a handsome centaur in love with the sorceress Circe.

She had one potion to turn him into something he didn't want to be, and another potion to turn him into something he desperately wanted to be, and she MIXED THEM UP. Why did she even HAVE the horse potion? Why was it even in the room to begin with?

And obviously making a potion to turn him back is impossible, so here's a potion that gives you amazing super powers. Because that's the easiest solution. Magic doesn't always make sense, people! It's not like science.

Oh, it was all Maldor's fault. That evil wizard! Observe the chart of the zodiac, which in the world of 1960s Superman comics controls the fate of us all! "Chuckle! We'll exile the super-horse to the constellation Sagittarius!" Or maybe 'Saggitarius'. Whichever.

And by a strange coincidence, Super Horse's exile just happened to be right next to where Supergirl's rocket came zooming past when she was blasted away from Argo City, which is a big chunk of Krypton that survived when the planet exploded and where Superman's uncle, who was also a scientist, lived, and when Krytonite radiation doomed Argo City he shot his daughter off in a rocket to Earth where she became Supergirl - that same rocket that just freed the Super Horse here. See how everything ties neatly together?

Here Comet the Super Horse joins Pinky Pie and the rest of the My Little Pony friends.

And then aliens attack the 1962 Seattle World's Fair in a desperate attempt to stop "grunge" right in its tracks. Can Supergirl and Comet save the future home of Mudhoney and Sub Pop Records?

Yes Supergirl! It's just like that dream you had last issue, which means that we really didn't have to write any new adventures for you this time, other than the whole lipstick branding thing, which is still kind of weird.

Is this the only time an alien invasion has been defeated by the super-kicks of a super-horse? I sure hope so. Look, even Superman is embarrassed by this whole thing.

Again, I don't want to read too much into this here, but a dreamy horse telling a young girl that the time is not ripe... at times this comic is one Modess sponsorship away from turning into one of those days in school where the boys go to the gym and the girls go to the home ec class and they're shown an informative movie about the exciting changes that are taking place in their bodies.

Oh no, "Mr. Greede" (subtle!) has sold Comet away to Hollywood! But remember - no one can keep a girl and her dream horse apart - not Hollywood or space aliens or puberty - nothing!

So there you have it, the secret origin of the super-horse; actually a centaur from ancient Greece turned super by accident and shot into space. No surprise they'd want to keep that one a secret.
